SPECIFICATION forming part of Letters Patent No. 750,109, dated, January19, 1904.

Application filed S teinber S, 1903. Serial No. 171,811. (No model.)

To all whom itmay concern r Be it known that L'WALTER HENRY HART, acitizen of the United States, residing at New Britain, in the county ofHartford and State IOv of Connecticut, have invented certain new anduseful Improvements in Back-Band Buckles, of which the following is aspecification.

This invention relates to buckles of thatclass employed to secureback-bands, traces, surcingles, and other straps or fastenings, and ithas for its objects the provision of a light, simple, and strong device,as will be hereinafter described.

In the accompanying drawings. Figure 1 is a plan view of the improvedback-band buckle, and Fig. 2 is a transverse section on line '2 2 ofFig. 1.

Like numerals designate similar parts throughout the several views.

Heretofore devices of the kind to which my invention relates have beenformed from plate and cast metal and have been heavy and cumlorous inorder that the necessary strength may be obtained, and it has thereforebeen a desideratum to produce a light and serviceable bucklesufliciently strong and rigid to withstand the severe strain to whichsuch a device is subjected, and this object has been attained by theimprovement now to be described.

Referring to the drawings, the numeral 5 designates the frame orbase-plate of the improved buckle, which is provided with raised hollowprotuberances or bearings 6 6, preferably struck up from the metal ofsaid baseplate and each having an open end 7 for the reception of theextremities of a web-holder, hereinafter described.

Punched from plate 5 is a hook 8, which may be curved to the formillustrated, or it may be of different shape, provided it does not fullycover the opening 9 made in the plate Fig. 2.)

Designated by 12 is the cross-bar of an improved web or band holder,which is bent at its'free ends, as at 13, said ends being inserted inthe open extremities of the hollow bossesfor protuberances 6,. asillustrated in Fig. 1, and to provide band-retaining surfaces on saidcross-bar short lugs or teeth 14: are swaged from the metal thereof, asalso shown in Fig. 1. In cross-bars heretofore known tome the teeth havebeen formed by cutting and removing the metal to produce inmanufacturing the cross-bars, a great desideratum in articles of theclass with which said bars are employed, and maximum strength andholding power obtained. This cross-bar overlies a slot 15 in thebase-plate, through which the folded end of the web is inserted after ithas been passed over the cross-bar.

Struck up from the metal of the base-plate is a hollow strengthening ribor corrugation 16, which extends in a line parallel with and adjacent tothe slot 15 in the front of said base-plate, the deflected ends 16 ofsaid corrugation extending along the sides of said plate to a pointopposite the protuberances or bearings 6, and connecting saidprotuberances is another hollow rib or projection 17. Radiating fromsaid corrugation 17 are hollow projections 18, having curved ends 18,which extend for some distance along the hook 8, adjacent to the edgesthereof, and thus serve to stiffen and strengthen the same; and tofurther strengthen said hook a hollow projection or rib 19 is formedalong and about on the middle of the same, said corrugation 19 extendingfor a short distance into the metal of the plate at the base of thehook. All of these corrugations are preferably struck up by a dieoperating on the back of the plate or of the metal of which it is made,and they thus form rounded external protuberances of pleasing and ornateappearance, and they are so disposed that they strengten the plate andits hook on the lines Where the greatest strain is exerted, and thusprevent it from buckling or collapse. In this Way a light, strong, andserviceable buckle may be produced from sheet metal, preferably steel,which Will Withstand all of the requirements of usage to which sucharticles are submitted.

Changes may be made in many of the details of the buckle Withoutdeparture from the invention, which is not limited to the exactconstruction described.

Having thus described my invention, What I claim, is-

1. A buckle having a slot for the reception of the ends, of the band, acorrugation adjacent to and parallel with said slot, bearings over theends of Which the corrugation extends, and a Web-holder journaled insaid bearings.

2. A corrugated, sheet-metal buckle having a slot for the reception ofthe band, a Webholder, hearings in which the free ends of saidweb-holder are inserted, and a corrugation for stififening the metaladjacent to the slot, said corrugation extending at its ends oppositethe outer extremities of said bearings.

3. A back-band buckle comprising a plate having a slot adjacent to oneend, a corrugated hook projecting from the plate adjacent to itsopposite end, bearings formed from the plate, a Web-holder having itsends inserted in said bearings, and corrugations extendinglongitudinally of the plate on each side of the slot, one of saidcorrugations having ends located opposite the outer extremities of thebearings.

4:. A back-band buckle formed from sheet metal, and comprising a platehaving a slot at its forward end for the reception of the end of theband, a corrugation parallel to said slot, a pair of bearings connectedby a corrugation, a Web-holder With ends mounted in said bearings, ahook, and corrugations extending from the plate and along the surface ofsaid hook.

In testimony whereof I afiix my signature in presence of two Witnesses.

WALTER HENRY HART.
